<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>CMAKE_THREAD_LIBS_INIT     - the thread library
CMAKE_USE_WIN32_THREADS_INIT - using WIN32 threads?
CMAKE_USE_PTHREADS_INIT    - are we using pthreads

<p>The compiler flag can only be used with the imported

recommended for new code.</p>
